BBC Wimbledon - HD vs SD Pics

daz200 · 01-07-2006, 7:47 PM

Couple of pictures comparing BBC HD to BBC1. Both pictures have had slight compression to make them uploadable to ImageShack. I think the difference is clear, and I am very happy with the image quality on Sky HD. Just need to get some more content, and reduce that noisy fan!

....obviously snaps taken off TV screen do not do the picture quality justice, but, I think provide a fair comparision (both pics have the same compression).

I'd noticed the difference when the players are serving, you make out the individual lines of the net on HD but can't see any of it on SD.
Is it just me or are people spending more time trying to notice how the picture's improved rather than actually watching the programme

You also have to take into account that the SD is a downconversion from an HD source - if it had been from an SD source they'd probably have looked worse.

Certainly watching in SD the Centre Court and Court No.1 pictures look better than the outside courts - sharper and less edge.

I was in comet yesterday and saw sky hd set up on a samsung 40" lcd.

It was very badly set up with the contrast and brightness set far far too high but apart from that I did notice that with the tennis, although the image when the camera was static was impressive it just seemed to exaggerate the blurring you see when the camera pans and moves.

Is this something others have noticed or was it due to a badly set up screen?

It just seems that because sd is less detailed to start with you don't notice this blurring to the same extent. I'm not implying there is anything wrong in this, because obviously the backgrounds etc will blur if the camera is moving with any speed, its just that I found it a little distracting although thats probably because I was studying the image rather than watching the tennis

Can't say I've noticed blurring myself (beyond what you get on SD anyway), but then on a badly setup screen you're far more likely to see it I guess.

Can you reupload pics please

did anyone else notice the irony? after the anti racist bit, they zoom in on the England dug out to see a UFF flag with the words No Surrender clearly shown (in HD it was clear, don't know about SD)

To my eyes motion blurring is not an issue - maybe LCD is the problem - Plasma seems fine.

I've yet to see an LCD that doesn't suffer from a degree of lag or blur with either HD or SD feeds. SD feeds seem to suffer from additional smearing in some cases - I guess due to more processing.

Can you please reupload them?

Wow you must have good eyes..

I've not seen any for years... I guess you know what you're looking for though more than I would.

What I would call smearing would be eg. the ball in wimbledon leaving a shadow behind it (so it looks like a comet, or in severe cases a yellow arc). Older LCDs used to do have that problem.. made using them fun if you were doing a lot of animation or even scrolling text quickly - but then I don't think anyone ever tried to display TV on LCDs of that era.. it'd just have ended up a mess.

My guess is we're actually talking about different things...

I think some in the plasma camp pick on blurring as being an area where plasma is better than LCD historically. However, if you look in the plasma threads, you see lots of people complaining about blur on the football, for example.

I must have good eyes too, or we're actually talking about different things, but I too have yet to see an LCD that doesn't suffer from some degree of motion smearing/blur/whatever on fast movement as a result of response times.

I spent ages looking at the best of them and it was still evident to me compared to the same image side by side on a plasma. So I went plasma for my main display.

What I did find though is that the problem is far less accute when playing HD material. It is barely noticable. If at all. My comparison in dealers was inevitably with SD material.

I do have a HD Ready LCD as well as a Plasma. And the motion smearing issue is like night and day when comparing SD and HD on the LCD. Which could be a consequence of the processing in the set of course, not the response time of the panel per se

If it was a property of the panel then SD vs. HD wouldn't make a difference - that sounds more like an artefact of the processing on the set (OTOH mine is great on both SD and HD.. not sure why SD would be worse on your set).
